EDGAR NALDRETT, or EDMONTON, ALBERTA, CANADA.-

BAIL ANCHOR.

Application filed March 27, 1925. Serial No. 18,909.

To all 107mm it may concern:

Be it known that I,

subject of the King of Great Britain,

of the city of Edmonton, in the resident EDGAR NALDner'r, a and Provinceof Alberta, Canada, have invented certain new and useful Improvements inRail Anchors, of which specification.

The invention relates the following is the to improvements in railanchors and an object of the invention is to provide an an chor whichwill pre vent creeping of the rail under the action of traflic and whichvertical movement ing under traflic the fastening spikes loose and thetie and down in the road A further object of provide a rail anchor 0also allows of a floating of the rail due to bendand by so doingprevents from being heaved from being pounded up bed. the invention isto f comparatively few parts and which can be readily manufactured andwhich can be readily placed 1n position on the tie and rail.

A further object is to construct the anchor so that any upsetting whilstpermitting of the veris prevented tical floating movement action of therail above intimated.

\Vith the above more important objects in view,

the arrangement and construction of hereinafter more par the inventionconsists essentially in parts ticularly described,

reference being had to the accompanying drawings, in which:

Fig. 1 is a side view of the anchor applied on the rail and secured tothe tie, the rail bein shown in vertical sectlon.

of the parts appear- Fig. 3 is a vertical sectional view at 3-3' Fig. lis a perspective View oi the tie plate.

Fig. 5 is a perspective view 01 the anchor block.

Fig. 6 is an enlarged view of the wedge.

In the drawing like once indicate corresponding eral figures.

The track rail is of presenting a head 1, We

detailed perspective characters of referparts in the sevthe customarytype b 2 and base 3. The

anchor which I provide embodies an anchor plate 1, similar pairs ofanchor blocks 5 and 6 and four similar wedges 7 The tie plate issubstantially rectangular and is placed beneath the rail and sits on thecustomary tie 8. The. body or that part of the tie plate lyingunderneath the rail is substantially horizontal and is normally elevatedabove the tie, tion by having the ends 9 and 10 of the plate incliningoutwardly and downwardly at a slight angle as best shown in Figure 1.The ends of the tie plate are fitted with spike holes 11 and 12 and theplate is fastened to the tie by spikes 13 and 14 driven through thespike holes. By making the tie plate arched in this manner, there is anatural tendency under the weight of traffic for the ends of the tieplate to embed themselves in the tie.

The opposite sides of the tie plate are provided with upstanding pairsof opposing similar lugs forming abutments or guides 15, 16, 17 and 18and these abutments are located outwardly a short distance from the railbase and have their inner faces 19 inclining upwardly and outwardly at aslight angle as shown. In the present instance, these abutments or lugsare formed from the material of the tie plate beingcut therefrom andbent upwardly. The pairs of an chor blocks 5 and 6 are more or-less of aU-shape and each presents upper and lower jaws 20 and 21 connected by anintervening neck 22. The jaws are adapted to span the edges of the railbase and the lower jaws when in place enter the openings or slotsindicated at 23 formed in the tie plate; There are. two pairs of wedges7 and these wedges are gradually tapered and present a large and smallend, both the width and thickness of the small end being less than thewidth and length of the large end.

When the device is to be used, the tie plate is slipped under the railfrom the side of the tie and is spiked in place centrally in respect tothe rail. The anchor blocks are then put in place by moving themlaterally into position and without raising the rail. The small ends ofthe wedges are then entered between the jaws 2 0 and the rail base beingheld in such posipermitting of and are driven home by a sledge. Thelarge ends of the wedges are all outermost. After the wedges have beendriven home, the inner or thin ends thereof are bent upwardly into aposition such as shown in dotted outline in Figure 3 which prevents themfrom withdrawing.

A rail carried by rail anchors of the type shown is prevented fromcreeping as the wedges hold the rail base to the anchor blocks and theinner sides of the anchor blocks butt against plate. The rail is alsopermitted to move or float vertically during'bending under trafiic as itwill be obvious that the anchor blocks can move upwardly in relation tothe abutments and whilst being maintained tightly fastened to the railbase by the wedges. Theslight inclination given the inner faces of theabutmen-ts is designed to give a slight clearance which permits the railand anchor blocks secured thereto to rise and fall under the action oftraffic. This floating feature prevents the spikes from being loosenedand avoids an pounding ofIthe-tie by the rail. The frictionsurfacebetween the anchor blocks and the abutments is sufiicienttoprevent any overturning ofthe rail under all-conditions.

If it should be desired to lock the rail against the floating actionabove described, it is only necessary .to have the inner faces 19 of theguides 15, 16, 1.7 and 18 inclining upwardly and inwardly in which .casethe guides would positively prevent any up movement of the anchorblocks.

lVhilst I have particularly described the floating featuie of the rail,it might be consider'ed however by railroad experts that sucli'is undei-rable and accordingly I have latterly mentioned the manner in whichthis floating can be avoided if desired. The article is none the-"less anoveltype of rail anchor regardless of whether'the faces 19 are verticalor-a're pitched slightly upwardly and inwardly.

lVlia't' is I claiiiias my invention is 1. The combination with altra'ckrail and tie, of a tie plate underlying :the rail and secured to the tieand provided with upstanding guides and members anchored to the edges oftherail base and slidably engag ing the guides, said guides andmemberspermit-ting of a movement of the rail in a vertical direction andpreventing any lateral displacement thereof duringsuch movement ment..

2. The combination with a track rail and tie, of a' tie plate underlyingthe rail and secured to the tie and provided with upstanding guides and,members anchored to the edges oftherail base and slidably engagingth'evguic'les and in contactwith the edges of theplates, said guides andmembers a movement of thrail the edges of the tie .tie, of

plate within the vertical direction and preventing any lateraldisplacement thereof during such movement and further preventing anycreeping of the rail.

3. The combination with a track rail and tie, of a tie plate underlyingthe rail and secured to the tie and provided with opposing upstandingguides spaced from the edges of the rail base and intervening membersclamped to" the opposite edges of the rail base and slidably engagingthe guides and abutting the edges of the tie plate.

4. The combination with a track rail and tie, of a tie plate underlyingthe rail base and provided with upstanding guides spaced from the edgesof the rail base and having slots provided in the edges thereof adjacentthe winner sides of the guides, members clamped to the edges of the railbase and extending into the slots and in sliding engagement with theguides.

5. The combination with a track rail and tie, of a tie plate underlyingthe rail base and spiked to the tie and providedwith upstanding guidesspaced from the edges of the rail base and having slots formed in theedges thereof within the guides, anchor locks gripping the edges of therail'base slidably engaging the guides and extending into, the slots.

6. The combination with a track rail and tie, of a tie plate underlyingthe rail base and spiked to the tie and provided with opposingupstanding guides spaced from the edges of the rail base and havingslots in the edges thereof underlying the rail base and within theguides, pairs of similar anchor blocks anchored to the edges of the railbase and making sliding contact with the guides andhaving the lower endsthereof underlying the rail entering the slots and contacting with theinner sides of' the slots.
